2 Claims. (CI. 20-40) This invention relates to window construction and,

more particularly, to ventilating windows.

An object of the invention is to provide a ventilating window having anovel frame that is angular in vertical cross-section and is providedwith movable sashes in the upper and lower portions of said frame,whereby the window is provided with transverse sashes that are angularlydisposed with relation to the horizontal and the angle thereof variable,as desired, in the vertical plane of cross-section of the window.

Another object of the invention is to provide a window that has itssashes disposed at an angle to the horizontal when closed and, thereby,reducing glare and reflection of light passing therethrough.

The invention also has for its objects to provide such means that arepositive in operation, convenient in use, easily installed in a workingposition and easily disconnected therefrom, economical of manufacture,relatively simple, and of general superiority and serviceability.

The invention also comprises novel details of construetion and novelcombinations and arrangements of parts, which will more fully appear inthe course of the follow ing description. However, the drawing merelyshows and the following description merely describes, embodiments of thepresent invention, which are given by way of illustration or exampleonly.

In the drawing, like reference characters designate similar parts in theseveral views.

Fig. l is an elevational view, as seen from the outside, of a windowconstruction according to the invention.

Fig. 2 is an enlarged vertical cross-sectional view as taken on line2--2 of Fig. 1.

Fig. 3 is a fragmentary horizontal sectional view as taken on line 3-3of Fig. 2.

Fig. 4 is a fragmentary cross-sectional view of a modification.

Fig. 5 is a fragmentary cross-sectional view of another modification.

Fig. 6 is a fragmentary cross-sectional view of another form of sash.

The window construction that is illustrated comprises, generally, aframe 10, and respectively upper and lower sashes 11 and 12 mounted insaid frame. The frame is set in a rectangular opening 13 provided in awall 14.

The frame comprises two similar sides 15 and, as shown in Figs. 1 to 4,said sides are connected by a transverse member 16. The sides 15 are oftriangular form and preferably of symmetrical or isosceles form. As bestseen in Fig. 2, each triangular side has its base 17 disposed verticallyin opening 13 and its two equal sides 18 extending outwardly from saidopening and joining at apex 19. While the included angle between thesides may vary, an obtuse angle in the nature of 150 degrees ispreferred. Thus, the protrusion of the sides from the wall is small withrelation to the vertical dimension of the frame sides. The transversemember 16 spans between said frame sides at the apices 19 thereof and,to complete the frame 10, upper and lower transverse members 20 and 21,respectively, connect the other angles of said frame.

In the above manner, frame 10 is provided with an upper opening 22 and alower opening 23, the former sloping downward and outward and the latterdownward and inward.

If desired, the two side frames may each be provided with a side windowsash 24 which may be fixed or, as shown in Fig. 3, may be hinged at 25to swing outward and increase the ventilation afforded by theconstruction.

The upper and lower sashes 11 and 12 are movably mounted in frameopenings 22 and 23, respectively. The sashes may be moved in the sameway or differently. For instance, each sash may be hinged to swinginward either on an upper or a lower hinge 26, as shown in the upperportion of Fig. 2; pivot on horizontal trunnions 27 so as to swingpartly inward and partly outward, as in the lower portion of Fig. 3; orboth pivot and slide, as shown in Fig. 4. In the latter case, thetrunnions 27 mount slideways 28 and the sash 29 is slidingly movable insaid slideways, as indicated by the dot-dash lines of Fig. 4.

Each sash is provided with a transparent pane 30 enclosed in a sashframe 31. While not shown, it will be understood that suitable latches,keepers, or the like, may be used to retain the closed and openpositions of said sashes.

In order to eliminate the obstruction of transverse member 16 and,thereby, provide an unobstructed space be tween the upper and lowersashes, when open, said member 16 may be omitted, as shown in Fig. 5,wherein said upper and lower sashes close against each other, as at 32.In other respects, the construction may follow the forms of Figs. 2 and4.

Instead of the panes30, the sashes may be provided with sets ofoverlapping transparent louvres 33, as shown in Fig. 6. When open, asshown by the dot-dash lines, said louvres provide spaces which, togetherwith the frame openings formed when the sashes are moved to openposition, create ventilating areas that are quite large relative to thesize of the window. One or both sashes of the window may be modified inthis manner.

While I have illustrated and described what I new contemplate to be thebest modes of carrying out my invention, the constructions are, ofcourse, subject to modification without departing from the spirit andscope of the invention. It is, therefore, not desired to restrict theinvention to the particular forms of construction illustrated anddescribed, but to cover all modifications that may fall within the scopeof the appended claims.

Having thus described the invention, what I claim and desire to besecured by Letters Patent is:

l. A wall window construction comprising a rectangular main framemounted in said wall, two side sashes each having an outline of atriangle with a vertical base, two slanting sides and an apex, the apexof said triangle projecting outwardly beyond the plane of said wall,said side sashes lying in two parallel vertical planes perpendicular tothe plane of said Wall, upper and lower sashes closing off the spaceoutlined by said main frame and the four slanting sides of said two sidesashes, two pairs of pivots mounted respectively on the upper and lowerslanting sides of said side sashes, and a U-shaped channel rotatablysupported by each pivot, said lower and upper sashes being slidablymounted in the respective U-shaped channels, whereby said upper andlower sashes are rotatable around the two pivots and slidable in and outalong said U-shaped channels upon the rotation of said sashes into openpositions.

2. A wall window as defined in claim 1, in which each of said upper andlower sashes includes a plurality of overlapping glass louvres.
